Mariners vs Pirates Prediction

Falter is coming off a subpar June, but he has a 3.62 ERA and 1.22 WHIP on the season, so he’s a worthwhile back. The Pirates are also having a hell of a week with six straight wins. Woo has a 2.93 ERA and 0.97 WHIP, but it doesn’t matter if the Mariners don’t give him run support. The Mariners have lost five of their last seven starts. We don’t have many chances to back the Pirates, but they’re having their best week yet. I’ll take a shot with the hotter team.
